The gut-brain axis is complex, and altering gut hormone signaling can have downstream effects on neurotransmitter systems that influence mood and emotional regulation
Future medicinal chemistry efforts may yield next-generation compounds with enhanced properties, including improved tissue selectivity, modified pharmacokinetics, or additional mechanistic activities that complement NNMT inhibition
Nicotinamide N-methyltransferase (NNMT) is a cytoplasmic enzyme that catalyzes the transfer of a methyl group from S-adenosyl-L-methionine (SAM, the universal methyl donor) to nicotinamide (the NAD + salvage precursor), producing 1-methylnicotinamide and S-adenosyl-L-homocysteine
Once your personalized plan is set, a nurse will clean the injection site (typically the arm or glute) and administer your shot using a sterile syringe and needle
Oral formulations: Investigated in capsule form, though bioavailability and efficacy are less well established
